When a door is provided on this large wall, generally, an opening frame called a door frame is arranged along the inner circumference of the opening provided on the wall.

The door frame A is composed of a vertical frame, an upper frame and a lower frame. Then, as shown in FIG. 6, for example, along the inner circumference of the opening 8 provided in the wall 7, the frame main body 2 is provided with its both ends substantially aligned with the wall surfaces 7a, 7a. It has been proposed that the vertical pieces of the parting material B, which is a frame material for an opening frame having a substantially L-shaped cross section, are fitted into the concave portions of the end surface of the frame body 2 so that the dimensions can be adjusted.

The frame body 2 is for building a door C as a fitting, and is provided with a door stopper 6. Further, the parting material B has a role of parting the wall surface there, and is formed of wood in a long shape, and is provided in the vertical frame and the upper frame of the door frame A.

[0005]

However, in the above-mentioned conventional technique, the vertical piece of the parting material B fitted in the concave portion of the frame body 2 is cut, and the thickness of the wall 7 on which the door frame A is installed is cut. In the case of dealing with the above, there is a problem that it is difficult to cut the parting material B along the longitudinal direction while securing a desired fitting margin. That is, the vertical piece of the parting material B made of wood may be bent in the longitudinal direction and cut, and in this case, a gap may be formed between the horizontal piece of the parting material B and the wall surface,
In some cases, a gap is created in the fitting portion between the parting material B and the frame body 2, and the frame body 2 is not reliably held.

The present invention has been made in view of the above circumstances, and an object thereof is to easily provide a parting member along the longitudinal direction when it corresponds to the thickness of a wall installed as a door frame, for example. An object is to provide an opening frame that can be cut and can surely secure a desired fitting margin.

[0007]

In order to achieve the above object, an opening frame according to a first aspect of the invention is a frame in which both ends thereof are substantially aligned with the wall surface along the inner circumference of the opening provided in the wall. In an opening frame in which a main body is provided and a vertical piece of a parting material having a substantially L-shaped cross section, which is composed of a vertical piece and a horizontal piece, is fitted into the concave portion of the end surface of the frame body in a dimensionally adjustable manner, It is provided with cut grooves at appropriate intervals which serve as marks for cutting during adjustment.

Therefore, in this case, both ends of the frame body are provided along the inner circumference of the opening provided in the wall so that they substantially coincide with the wall surface, and are composed of a vertical piece and a horizontal piece having a substantially L-shaped cross section. When adjusting the dimension of the opening frame in which the vertical piece of the parting material is fitted into the recessed portion of the end face, it is possible to cut using the cut grooves at appropriate intervals provided in the vertical piece of the parting material as marks.

The opening frame according to claim 2 is the same as that according to claim 1.
The described vertical piece has a hollow inside, and has an appropriate number of reinforcing ribs formed therein so as to substantially match the kerf spacing of the cutting marks.

Therefore, in this case, a suitable number of reinforcing ribs, which are formed in the hollow portion inside the vertical piece and substantially match the kerf spacing of the cutting marks, are used as boundaries.

The opening frame according to claim 3 is the same as that according to claim 2.
The described kerf is formed by cutting it off beforehand.

Therefore, in this case, the vertical piece can be cut by cutting only the side opposite to the kerf.
